[movies]Time And Clocks - Milan Herzog; Physical Science Study Committee. Physics.; Educational Services, Inc.; Modern Talking Picture Service, inc.
In this classic Physical Science Study Committee (PSSC) film, MIT professor John G. King discusses the concept of time and shows various devices used to measure and record time intervals from 1 second down to 10 seconds. He points out that the accuracy of a clock can be judged only by comparison with another clock. The question of what time is, psychologically and physically, is raised briefly as well as the question of a possible limit to the subdivision of time...

[movies]Random Events - Physical Science Study Committee. Physics.; Physical Science Study Committee.; Modern Talking Picture Service, inc.
Professors Donald Ivey and Patterson Hume show how the over-all effect of a very large number of random events can be very predictable, using several unusual games to bring out the statistical nature of this predictability. They explain the predictable nature of radioactive decay in terms of what is shown. For more info on PSSC, its history, and films, visit http://www.afana.org/psscfilms.htm

[movies]The Millikan Experiment - Educational Services, Inc.; Modern Talking Picture Service, inc.; Physical Science Study Committee.
Dr. Alfred G. Redfield performs a simplified Millikan experiment photographed through the microscope. Substituting standard spheres for oil drops, he demonstrates the effect of X-rays and the relationship of the charge to the velocity of the spheres. Professor Francis L. Friedman explains that charge comes in natural units that are all alike, and points out numerous changes of charge.

[movies]Interference Of Photons - Physical Science Study Committee.; Educational Services, Inc.; Modern Talking Picture Service, inc.
MIT Professor John G. King performs an experiment in which light exhibits both particle and wave characteristics. He uses a very dim light source, a double slit, and a photomultiplier in such a way that less than one photon is in the apparatus at any given time. King points out that the characteristic interference pattern is pointed out by many individual photons hitting at places consistent with the interference pattern, and discusses the implications of this action...

[movies]Frames of Reference - Richard Leacock
This PSSC film utilizes a fascinating set consisting of a rotating table and furniture occupying surprisingly unpredictable spots within the viewing area. The fine cinematography by Abraham Morochnik, and funny narration by University of Toronto professors Donald Ivey and Patterson Hume is a wonderful example of the fun a creative team of filmmakers can have with a subject that other, less imaginative types might find pedestrian.

[movies]Magnet Laboratory, A - Richard Leacock
In the hands of another director, the inner-workings of a magnet laboratory could have caused a whole classroom to fall asleep of boredom. No so when Leacock was hired to produce this twenty-minute version of lab mayhem. Try this: six researchers in a lab at MIT in the late 1950's show-off the power of electro-magnets, and in the process, accidentally set an experiment on fire(Leacock says he did a retake without the fire, but preferred the immediacy of the fire sequence and kept it in)...
